Which process destroys all microbial life on an object?

Which process destroys all microbial life on an object?

• A. Cleaning
• B. Contamination
• C. HIV
• D. Sterilization

Answer: (D)

Sterilization is the process that guarantees destruction of all microbial life on an object, including bacterial spores, which are highly resistant. Cleaning only removes visible soil and reduces the microbial load but doesn’t kill every organism. Disinfection lowers the number of viable microorganisms on surfaces but may not kill spores or all microbes. HIV is a virus, not a method, so it isn’t a process used to treat objects. For items that must be completely free of microbes, sterilization is the appropriate requirement.
